Answer:
we know that when we express km/h to m/s we multiply5/18
but
from m/s to km/hr we multiply 18/5
according to the question we can write the problem in the following way
as we know m/s to km/hr we have to multiply18/5
the we are given that speed =121/2 m/s
in km/hr the solution will be
121/2 × 5/18=16.8055555 km/hr
=17km/hr
Hence ,the answer is 17 km/ hr (verified)
